Actually, even if you keep the carpet, is always a good idea to seal the floor on the inside. Seen too many jeeps with floors rusted out, and the real issue is from the inside holding moisture against the floor rusting it out from the inside, not from underneath.

yeah mine had rust from the inside, but that was my fault. Got water in from the bottom of the doors when a puddle dropped off. Actually my avatar is where it happened haha, but yeah there was a good amount of rust there. Don't think I'm saving the carpet, but I'll see how I like this.
